CleanPath existed all along (path.go:118) — earlier grep had a stray
quote that hid it. Example now demonstrates actual behaviour:
redundant separator removal and .. resolution.
Removed duplicate CleanPath_Good test that conflicted with existing.
546 tests, all pass.

33 new examples across 8 dedicated files. Removed phantom CleanPath
(in RFC spec but never implemented — spec drift caught by examples).
545 tests total, 84.8% coverage. Every major primitive has compilable
examples that serve as test, documentation seed, and godoc content.
